GQ GMC-600 Geiger Counter Radiation Detector Dosimeter Alpha Beta Gamma X-Ray Tube SBT-11

Got this meter as it is able to detect alpha beta and gamma decay unlike some cheaper models which only detect beta and gamma. This allows it to indirectly detect the presence of radon gas (an alpha emiter). i used it to check my basement bedroom and sure enough, almost immediately found a 50% increase in activity where i sleep. While in my case, the levels are still within safe exposure limits (further testing will have to be done though), they say radon gas kills more people than drunk drivers do. Better safe then sorry and 250$ is a pretty small sum to put on one's long term health. If you live in a basement, around alot of granite or surrounded by concrete, might be worth a buy just for the peace of mind if nothing else

Es un medidor de radiación muy sencillo de usar. Viene con diferentes modos de operación para mostrar la evolución de las medidas con el tiempo, así como con jack para auriculares.El dispositivo luce robusto y no es excesivamente grande, puede transportarse fácilmente. Además viene acompañado de una bolsa protectora para guardarlo.De momento contento con la compra.

Small portable radiation detector that measures alpha, beta and gamma radiation at an affordable price. It is being used to check rock samples from my rockhounding hobby. Being plastic, it is best to carry it in the included pouch. The included “manual” is almost useless. One needs to download the online manual.
